Detail X indicates a proposed shoreline slope that is graded at 2:1 and reflects the estimated normal pool level and the estimated height of the subject shoreline above the normal pool level. Calculation 1—Impact Area Below Normal Pool Level (Item 8 on NCDEQ Form SSGP 09-2020) Area of Impact = Shoreline Length x Depth* x Slope = (244') x (1') x (2) = 488 sq.ft. *For this calculation, an average water depth of 1 ft. has been assumed. This will produce a conservative overestimate of the stabilization impact area. Calculation 2—Impact Area Above the Normal Pool Level (Item 9 on NCDEQ Form SSGP 09-2020) Permanent Impact From Shoreline Stabilization Measures Height of Bank Above Normal Pool Varies Across the Shoreline Estimate 80 LF of Shoreline = 3 ft. Above Normal Pool Estimate 84 LF of Shoreline =4 ft. Above Normal Pool Estimate 80 LF of Shoreline = 5 ft.Above Normal Pool Area of Impact = Length x Height x Slope = ( 8 0' x 3' x 2) + ( 8 4' x 4' x 2) + ( 8 0' x 5' x 2) = 480 + 672 + 800 = 1952 sq. ft. Impact From Construction Above Shoreline Stabilization Assume 5 ft. Wide Zone Area of Impact = 244' x 5 ft. = 1220 sq.ft. Total Area of Impact Above Normal Pool Level = 3172 sq.ft.
